Question

unit of n in current carrying solenoid​

Answer 1

Answer:

the SI unit for n is m-¹

Explanation:

1- For a current-carrying solenoid, the formula is

B=μ0nI

•B is the magnetic induction,

•μ0 is the permittivity of free space

•n is the number of turns per unit length

•I is the current in the solenoid.

2- Here ,n refers to the number of turns per unit length.

As we know the solenoid is in form of a circular ring.

So, the length will become the circumference of the circle.

n = number of turns /circumference of circle

n= n / 2πr

Therefore, the SI unit for n is m-¹
